He had now, in 1339, put the first hand to his epic poem, the Scipiade; and one of his friends, De Sade believes that it was the Bishop of Lombes, fearing lest he might injure his health by overzealous application, went to ask him for the key of his library, which the poet gave up.

The Bishop then locked up his books and papers, and commanded him to abstain from reading and writing for ten days.

Petrarch obeyed; but on the first day of this literary Ramazan, he was seized with ennui, on the second with a severe headache, and on the third with symptoms of fever; the Bishop relented, and permitted the student to return to his books and papers.
Petrarch was at this time delighted, in his solitude of Vaucluse, to hear of the arrival at Avignon of one of his dearest friends.

This was Dionisio dal Borgo a San Sepolcro, who, being now advanced in years, had resigned his pulpit in the University of Paris, in order to return to his native country, and came to Avignon with the intention of going by sea to Florence.

Petrarch pressed him strongly to visit him at Vaucluse, interspersing his persuasion with many compliments to King Robert of Naples, to whom he knew that Dionisio was much attached; nor was he without hopes that his friend would speak favourably of him to his Neapolitan Majesty.
